i would say about 8 years old. well it depends how long a chicken can live.
I'm not a chicken exspert so I'm not sure but I'm pretty sure that's it.
After 18 weeks
about nine ten months.
why does my 12moth old chicken lay a soft shell egg then i see blood on the outer shell
The very young, the very old and of course the male chicken which is called a rooster.
there's not enough day light and its too cold.
roughly 18 weeks from birth :)
when they are 5-6 months old
Maybe its too old to lay eggs now or its too cold to lay eggs
No. A dinosaur and a chicken are too different; one won't convert overnight into the other.
A boiler chicken is a bird that has been kept for egg laying but has grown too old to continue to lay eggs properly. The bird is therefore quite large and may be a bit tough and needs to be well boiled to make it fit to eat.
no not every chicken does.
Any breed of chicken can lay eggs for breeding if they are fertilised.
